Product Description:

Introduction:Tower crane is used to lift, lower and horizontally move materials in construction and other industry. It has large lifting capacity and lifting height, wide moving range, and can rotate. It basically consists of base foundation, mast, slewing unit, working jib, counter jib, counterweight, hook, and operating cabin.

Features:

1. All the components are designed to minimize the total number of trucks required to transport. The jib components can house the jib ties to make transport easier and quicker.2. With the factory-performed pre-reeving and the auxiliary winch supplied as standard, assembly of the jib and counter-jib ties can be carried out quickly and in total safety.3. The mechanisms are always used at full power. When hoisting, the speed is optimized according to the load and command used. In distribution, progressive variation of speedand the maximum speed are adapted to the weight of the load. In orientation, there is controlled proportionalspeed with optimal acceleration and deceleration in accordance with the maximum admissible torque for the mast.4. DVF DistributionThe jib-footDVF mechanism is easily accessible in total safety.Progressive speed variation by proportional control.The speed depends directly on the controls manipulated by the crane operator.To make driving the crane easier, 2 hard spots integrated into the controlsprovide better pinpointing of the speed.5. RVF + orientationThe RVF Optima + orientation enables gentle rotating movements without jerking.Fully integrated progressive control.Driving adapts to the behavior of the crane operator: The slow-down phase of the jib is managed by the frequency variator. Or by an inverted command in the slow-down phase, called a "counter-orientation" command. As a result, the crane operator can control stoppage.

Q:What is the minimum radius of a tower crane?

Luffing jib crane luffing mechanism to control the lifting radius, which is lifting and landing boom.At the minimum radius, the boom is angled to the vertical.

Lifting machines are inspected regularly every two years, and explosion-proof lifting machines shall be inspected regularly every year. Must have the corresponding inspection qualification inspection.

Q:Tower crane, this model inside each letter number represents what meaning, ask the great God to inform.TCT7527-20, TC6015A-10E

The basic parameters of the tower crane: a working range: refers to the center of rotation of the lifting hook up center and tower crane horizontal distance. Two, weight: rated lifting weight and maximum weight. The maximum rated lifting weight refers to the biggest boom in quality to allow the minimum amplitude of the tower crane, is one of the main technical parameters of the tower crane. Three, lifting...

Q:In what circumstances should a tower crane be demonstrated by an expert?

(two) lifting equipment with lifting capacity of 300kN and above; climbing within height 200m or aboveDemolition of heavy equipment.

Q:When the tower crane top height is more than meters

(two) lifting equipment installation with lifting weight 300kN and above; demolition work of climbing crane within height 200m and above.The installation and disassembly of the tower crane in accordance with the provisions of the above provisions shall be verified by the expert panel.

Q:How many tons of tower crane QTZ80A lifting?

QTZ80A 80 refers to the lifting torque of 80 tons after lifting meters.

Q:What does "slewing up" and "under rotating" in the slewing form of a tower crane mean?

In short, when the tower rotates in the form of a tower, the tower is stationary (ie does not follow the rotation), and the form of the lower turn is the tower will rotate.

Q:What kind of bodies are tower cranes made of?

Tower crane is composed of three parts: working mechanism, metal structure and power unit, and control system. The composition and function of the three parts are outlined below.

Q:How much is a team of 40 tower crane

Tower crane rental generally do not rent pricing, can not count number, not today is installed, removed tomorrow!Usually on a monthly basis, with or without use!
